TopoSynth: Topological Structure

Posted on August 23, 2010 by moniker

DLFL Background As I had mentioned in the last post, the topological inspiration for TopoSynth is derived from TopMod and particularly the doubly-linked face list (DLFL) data structure.  The DLFL makes it particularly straightforward to always maintain a 2-manifold mesh … Continue reading →
